The Mines and Geosciences Bureau Regional Office 6 (MGB-6) issued a landslide and flood advisory to the local government units in coordination with the field offices (PENROs and CENROs) of the DENR Regional Office 6 and the Department of the Interior and Local Government here in Region 6.
In the advisory, MGB-6 warns that the Low Pressure Area and Inter-Tropical Convergence Zone (ITCZ) may trigger landslides and floods in the areas of Western Visayas classified as susceptible to landslide and flood based on the Geohazard Maps (1:10,000 scale). Roads and bridges prone to landslide and flood hazards may also be closed if necessary based on actual conditions on the ground.
MGB-6 refers to the Weather Advisory No. 1 and Thunderstorm Advisory No. 19 issued by PAGASA-DOST at 4:00 PM on May 3, 2020. “The Low-Pressure Area was estimated based on available data in the vicinity of Marihatag, Surigao del Sur or at 60 km Northeast of Hinatuan, Surigao Del Sur (8.8°N, 126.0°E) embedded along the ITCZ affecting Mindanao. The combined effect of the LPA and ITCZ will bring scattered light to moderate with occasional heavy rains over Mindanao, Visayas, and Bicol Region.”
“Moderate to occasionally heavy rain showers with lightning and strong winds due to thunderstorms are expected over Negros Occidental (Calatrava, San Carlos City and Toboso) which may persist within 1 to 2 hours and may affect nearby areas. However, these weather conditions may persist in all of Western Visayas,” PAGASA said.
“Residents of the aforementioned areas, especially those living in areas identified to be highyl susceptible to flooding and rain-induced landslides, are advised to take appropriate actions, coordinate with the local disaster risk reduction and management offices, and continue monitoring for updates, especially the Thunderstorm/Rainfall Advisories and Heavy Rainfall Warnings to be issued by PAGAS Regional Services Divisions.”
